Intro riff to 'Baying of the Hounds'

[The Antihero]

Apologies if this has been asked a zillion times but does anybody know exactly what instrument the keys are?

It sounds kind of like a Hammond organ but there are parts that sound more like a synth. Maybe it's a combination of both?

 

[Vega Skater]

I can't answer your question, but that intro always reminds me of Michael Jackson's Moonwalker on Sega Mega Drive/Genesis. Ha I love it.

 

[Nailed Reaper]

Synth? Oh, dunno... I always thought it's 100% Hammond sound.
